Product Description

Like the Kershaw Half-Ton, but need a bigger knife? Wish granted. It’s the One-Ton. The Kershaw One-Ton (#1447) has a wide, fat blade (even thicker than the Half-Ton) ready to take on any and all heavy-duty tasks. The handle is machined G-10, but only the front has a liner, so this big knife is not as heavy as you’d expect. Carry it tip-up or tip-down, but definitely carry it.

Most Helpful Customer Reviews

Had a friend with a smaller version of this knife, and thought it was a great little cutter. I figured I'd go full one ton and one up him, but I was wrong. The knife overall is just "okay". The knife would be rockin five full stars if it wasn't for the grip. Being textured on one side and smooth steel on the other, it's tough to open and close. That might change with some work, let the knife loosen up a bit, but I still don't see that I'm going to be happier about that grip. It's a mood killer, for sure.

Following up: Okay, so I've worked with the knife a bit, and over a couple days the action's loosened up a little. Also, with just a little adjustment in my grip, opening the knife is getting easier. My complaints about the grip are still there, but I'm making adjustments myself to deal.

And it is worth it... I broke down a box the other day after buying a new lawnmower, and decided to try this knife out instead of a box cutter. Holy (insert expletive of choice here), this knife slices like you wouldn't believe. Overall, my review is going to go from a three to a four. That one star is still over the grip, but I'm learning to live with it.

The Kershaw One Ton is a decent knife, once you learn to deal with the issues. Opening the blade can be a bit difficult, but with practice, it will work out. Obviously, this would not be a good knife for wet environments, as bead-blasted finished steel is prone to rust. But my main issue is with the grip and the form factor. It's very thin closed up, which makes it insanely easy to carry, like I wasn't carrying a knife at all. However, that thin form factor is an issue when it comes to grip. The grip on the knife is doable, but it's not comfortable. Also, the G-10 on one side and the steel on the other side looks awkward.On the plus side, the blade shape is really good for utility tasks, and although it's not a good stabbing shape, it comes in useful. And it's very sharp out of the box.It's not a bad knife for the money. If you like the blade shape, buy it, but I can't help but think that there are other knifes around this price range that might be easier to deal with.

To start, I've had 100's of knives, and tested all types for my needs. This is an EDC (everyday carry) knife for me. I've had 3 or 4 of these, and only bought another when one was misplaced, or taken away (long story). I've never seen one reach the end of its life or get damaged. I have multiple carry knives, as I regularly leave it in a spot I'm working, so I grab another one that's closer and carry that for awhile. I like the variety, as each knife has benefits that others don't. I keep coming back to this knife and buying more for 3 reasons:

1. It's super light with only a liner on one side. I don't baton wood with it or anything (well, not often), and I've never had any problem with the overall structure being weak from it's lightness. It really is significantly light for it's strength.

2. The flip open functionality is the fastest and smoothest of all my knives with that style of opening. I take it apart and clean it up from time to time, but it takes a lot to get enough grit in there to slow it down to that point (and I'm a bit obsessive about cleaning/sharpening). Once cleaned, it's fast and smooth again, usually for months of daily use. It's just quick, and I've had more than one person say something like "I thought switchblades were illegal."

3. The blade simply cuts well, and holds an edge. I haven't measured, but it seems the angle of the blade edge is smaller than most other knives out of the box (think razor vs chisel). Even with the more gradual edge, it doesn't dull quickly. I know various alloys have different strengths, and I don't even remember what this one is made of. I've just gone through a few now and love how long it cuts and stays sharp.Read more ›

I like it, but for some reason, I just love the 3/4 ton better. I don't know why. It just has a better feel in the hand. I actually ended up giving this one to a friend. They're incredible knives though, very sturdy, sharp, well made. no complaints here.

The blade on this knife seems bigger in person. It has a lot of belly and comes razor-sharp out of the box. Please read up on the specs for this knife so that it will help you decide if this is the purchase for you. There are some idiosyncrasies that I hope to deal with though. The detent on the blade seems very tight and hard. This makes the blade open slower than I would like. I think the frame lock partially is to blame. I can flick this blade out with my thumb but it is difficult. This knife was so affordable that I am going to use it as an example knife to make improvements on.

The improvements will hopefully consist of: 1) Replace the teflon pivot washers with phosphor bronze washers. These washers are found in higher quality knives and provide better slippage. 2) Sand/Polish the blade to a mirror finish in order to eliminate the bead blasting which comes on the blade. 3) Polish the end of the frame lock in order to provide more slippage.
